Just as easy to install as the OEM filter. Seems more responsive to the accelerator, esp. at higher altitudes (9000 FT). Ordering one for my 2013 Ford Focus!

Appears to be giving me a few more miles per gallon, even around town (33-2200). Used to get 16-17 local on my '04 MDX, now almost 20mpg. On the HWY on a 1100mi trip I make fairly often I was lucky to get 21, this includes the WV mountain! This last trip I got 22.4 on the return which is usually worse than the trip there. Seems also to have increased performance having driven longer, if &nbsp;that makes sense?

Noticed some improved acceleration...smoother. Not convinced this filter had any significant impact on my mileage. Overall, I do feel good that it is in my car and that I don't have to worry about future replacements.
